Diving into Dynamic Range

Sometime back I took issue with a single assertion you made about the visibility of jitter. (I still do.) Other than that, I found the video to be excellent. I was prompted to watch more of your videos. They are universally EXCELLENT! I don't know anything about films you've been involved in making but I suspect they're great as each of the "Filmmaker IQ" videos I've watched has been informative, well researched, well paced and a delight to watch.
FIVE GOLD STARS! 🌟🌟🌟🌟🌟

Im having a lot of issues with the dynamic range on the Hitachi uhd 4000. Followed every procedure and still, the whites look crazy high

hi again i have three questions which are semi related to the video but more on a general understanding of digital signal processing.
1. I read online about a concept called quantization which is teh assignement of taking basically infinite numbers and converting them into a finite number of values. does this mean that before the concept of quantizing, the numerical code values produces by teh a/d convertor are much larger/ more infinite, and only during quantizing does it limit the code values to the amoutn of bits availble. e.g. 8 bit- 256 available code values
2. i dont really understand where in the process of assigning numerical code values to teh different amoutn of voltage (produced by teh photosite) does linear encoding vs non linear encoding occur.
3 is gamma correction a replacement of linear encoding or is it something that occurs after wards
4 finally not really a question, but i have made like a some notes on this concept of signal processign and encoding and was wonerding if it would be possible for you to review it to check that i ahvent confused myself or wrote soemthign wrong.

Umm John, I am re-watching this video because your explanation of raising the ISO was over my head. If I am not mistaken, or getting crazy, you updated it and added new elements, especially the cloud example. Now I get it. Thanks so much!. This is a great video!. Cheers

Thanks for the great explanation which inspires to be dwelve deeper in to this topic..🙏

maybe one of the most helpful videos on ISO and dynamic range. Thank You so much.

Hello. I would like to know if you know any program to lower only exclusively the brightness of the most luminecent colors of my screen, such as white, like a gamma curve that can be modified in multiple points, not the standard gamma curve. As a Knee, as you call it, that only lowers the high end brightness. The whites and soft greys burn my eyes. I cannot get help anywhere else. Thank you for your time if you respond.

I'm addicted to this channel. superb work!

Thank you for the video. it helpful for sure. Dynamic led-machine is good idea but using ND gel-filters NOT. (I also tried similar idea 7-8 years ago). After 3-5EV it have heavy color shift. Also steps are far from ideal (my guess it due to fiber-optic).

thx

I learned SO MUCH from this video. And still, half of it is over my head. What an awesome video!

Easily the best explanation of light/metering/curves/log/raw... you name it. This is gold. Even the "old" way of thinking ISO as one corner of "exposure triangle", replaced with true scientific knowledge... just priceless! I sincerely thank you, Sir, for making this video. Once more, easily the best tutorial if someone wants to truly understand light in cameras, both still and video.

Separate raw from log is essential for still shooters thx

Recién empiezo a estudiar algo de fotografía y no entendía porque muchas paginas me decían que subiera el ISO en situaciones de poca luz cuando por experiencia en post ya me había dado cuenta que era obtenía mas información haciendo lo contrario. Gran explicación!

Wow, blew my mind many times!

These videos are so amazing. Thank you!

I learned a couple things and comprehended a few concepts that where murky in my mind... great video on a stupifying subject!

🙃great explanation

Fucking awesome!

Great video and excellent explanation. But I have a question. So, how do we find out the appropriate dual ISO combination of different cameras if do not have the chart of DR as shown in your video? Optimum combination of ISOs (dual ISO) for predominantly dark scenes and for predominantly bright scenes? And secondly, what is the role of ETTR?

This was a great video!!! Very informative!!!!

i take it that means using a regular camera or smartphone camera to get the most possible detail the exposure should be done with low iso and a exposure time thats long enough to over expose the bright part of the image without clipping it so that later in photo editing software it can be darkened to and that would bring detail that wouldnt have got captured?

This is one awesome video. I cannot thank you enough; this information was extremely well presented and the presenter was great, too. Thank you so much!!!!

for an exhibition of his experience , john uses camera sensors of only green and blue but not red ,and he composes red by the color of his shirt which is actually white :p

If our scopes says our highlights our not clipping, does that mean that regardless if we're shooting log or raw, we're exposing correctly and making sure the dynamic range of our cameras are capturing the necessary range for the scene?

really informative! Thank you for sharing that valuable data!

Awesome video, thanks

This video is one of the best, ever!

You've taught me more about moviemaking and cinema history than any film school could ever teach. God bless you John.

@filmmaker Iq Any idea how much Dynamic Range is lost when using Creative Styles versus S-Log in Sony Cameras? Or perhaps even Cine 4 Picture Profiles versus S-Log?

Absolutely a great explanation of dynamic range! Question where can I find a chart for dynamic ranges for Canon and DJI? Their sites do not post them?

I cannot even believe this video. I am in AWE! How do you not have 1 million subscribers yet? You are a very smart, well spoken instructor! Wow!

Hey, thanks for all the video ! I have one question do you think shooting log is a bad choice in an high key shooting situation let say a white studio with a lot of subtle change in the above middle grey area ?!
thanks

Hey John ,I love your videos , you teach me somethings that no one do before , and you do it for free . i Wish you the best ❤❤❤

What makes this range dynamic, rather than static?

This was the most informative video on HDR I've ever watched!

Dude. Just outstandingl info there!

This video is worth money. I wasn't even here for photography, but trying to master the gamma & linear concepts.

Greeeat content 👍👏👏👏

Does itt also works for photography or just video?

You went full dork with this one. I love it.

Jeeeeeeeeeezzzzzzz

Every 6-months or so I come back to watch these videos to refresh my understanding of exposure, gain and dynamic range. And each time I watch there is a new "Ah Ha" moment when I recall a shooting situation where I gapped on an important part of this. I typically shoot RAW/ETTR but for quick turnaround jobs I will switch to camera processing and then "forget" higher ISO for brighter scenes and lower ISO for darker scenes for example. Thank you for taking the time to explain this, particularly to an old film guys like me who is trying to unlearn the exposure triangle myth.

Awesome work, I think I'll have physics students watch this video, just taught sound intensity and level (dB) and this would be a good follow on topic!

I thought I knew a thing or two but after watching this I'm both more confused and more enlightened 😂
